Objects can be created by calls of the form new("CoImp", ...).
Slots
Missing.data.matrix:
Object of class "matrix". Original missing data matrix to be imputed.
Perc.miss:
Object of class "matrix". Missing and available data percentage for each variable.
Estimated.Model:
Object of class "list". The list contains:
model
the copula model selected and estimated on the complete cases.
dimension
the dimension of the model.
parameter
the estimated dependence parameter of the model.
number
the index of the estimated model in the list of models given in input.
Estimation.Method:
Object of class "character". The estimation method used for the copula model in Estimated.Model. Allowed methods are in fitCopula.
Index.matrix.NA:
Object of class "matrix". Matrix of row and column indexes of missing data.
Smooth.param:
Object of class "numeric". The values of the nearest neighbor component of the smoothing parameter of the lp function.
Imputed.data.matrix
Object of class "matrix". The imputed data matrix.
Estimated.Model.Imp
Object of class "list". The list contains:
model
the copula model selected and estimated on the imputed cases.
dimension
the dimension of the model.
parameter
the estimated dependence parameter of the model.
number
the index of the estimated model in the list of models given in input.
Estimation.Method.Imp
Object of class "character".The estimation method used for the copula model in Estimated.Model.Imp. Allowed methods are in fitCopula.
